Hair care???

First off: do what you want to do, not what others want you to do!

Second: my hair used to be down to my butt. To keep it nice and healthy I used extra virgin olive oil on the ends once a week (Youtube tutorials galore!). Make sure it's the ends tho, because if you want to do your whole hair it's a different process when the oil and the scalp are involved.

Jojoba oil can work wonders. You can find it at places like Whole Foods or order it online. It really just takes a few drops. Even for a deep oil treatment I might use half a teaspoon. (And my hair is very long, just cut it back to knee-length.)

Also, be sure to use a good shampoo and conditioner that are appropriate for your hair type. My hair is very straight and somewhat oily. I've had good results with the Burt's Bees and Giovanni products.

Using heated styling appliances like blow dryers, curling irons, and flat irons can cause damage and lead to dryness also. So you may want to avoid or minimize using these things, especially on the ends of your hair.

I hope you find something that helps and can enjoy wearing your hair long. If not, talk to your husband again. No one should have to deal with having a hairstyle they don't like.
